WebBrowser Cookie

WebBrowser的Cookie操作

.在WebBrowser中获取Cookie

CookieContainer myCookieContainer = new CookieContainer();

string cookieStr = webBrowser1.Document.Cookie;
string[] cookstr = cookieStr.Split(';');
foreach (string str in cookstr)
{
    string[] cookieNameValue = str.Split('=');
    Cookie ck = new Cookie(cookieNameValue[].Trim ().ToString(), cookieNameValue[].Trim ().ToString());
    ck.Domain = "www.google.com";
    myCookieContainer.Add(ck);
}

WebClient设置cookie!
WebClient wc = new WebClient();
wc.Headers.Add("Cookie", "PHPSESSID=" + cookie + ";");
// 注意，这里是Cookie，不是Set-Cookie
byte[] re = wc.UploadData(Global.RootPath + "test.php", new byte[]);
System.Text.UTF8Encoding converter = new System.Text.UTF8Encoding();
string str = converter.GetString(re);

. 在WebBrowser中设置Cookie
public partial class WebBrowserControl : Form
{
        private String url;

        [DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)]
        public static extern bool InternetSetCookie(string lpszUrlName, string lbszCookieName, string lpszCookieData);

        public WebBrowserControl(String path)
        {
            this.url = path;
            InitializeComponent();

            // set cookie
            InternetSetCookie(url, "JSESSIONID", Globals.ThisDocument.sessionID);

            // navigate
            webBrowser.Navigate(url);
        }
}

.将WebBrowser的cookie信息传给HttpWebRequest

先建一个"CookieContainer" 把WebBrowser中的Cookie保存在里面

//在WebBrowser中登录cookie保存在WebBrowser.Document.Cookie中
CookieContainer myCookieContainer = new CookieContainer();

//String 的Cookie　要转成　Cookie型的　并放入CookieContainer中
string cookieStr = webBrowser1.Document.Cookie;
string[] cookstr = cookieStr.Split(';');

foreach (string str in cookstr)
{
    string[] cookieNameValue = str.Split('=');
    Cookie ck = new Cookie(cookieNameValue[].Trim().ToString(), cookieNameValue[].Trim().ToString());
    ck.Domain = "www.abc.com";//必须写对
    myCookieContainer.Add(ck);
}

HttpWebRequest hreq = (HttpWebRequest)HttpWebRequest.Create("http://www.abc.com/search.asp");
hreq.Method = "POST";
hreq.ContentType = "application/x-www-form-urlencoded";

//自己创建的CookieContainer
hreq.CookieContainer = myCookieContainer;

string postdata = "id=2005&action=search&name=";
byte[] byte1 = Encoding.ASCII.GetBytes(postdata);
hreq.ContentLength = byte1.Length;

Stream poststream = hreq.GetRequestStream();
poststream.Write(byte1, , byte1.Length);
poststream.Close();

HttpWebResponse hres = (HttpWebResponse)hreq.GetResponse();
